Answer:
 $490
Step-by-step explanation:
For computing the amount of shrinkage first we have to find out the ending inventory which is shown below:
= Beginning Inventory + Purchases - Inventory Sold 
= $12,000 + $38,000 - $35,210
= $14,790
 Now 
Actual Ending Inventory = $14,300
 So, 
Shrinkage amount is = Ending Inventory as per Book Value – Actual Ending Inventory 
= $14,790 - $14,300
= $490
